JOHN B. MORRIS, OF CINCINNATI, OHIO, ASSIGNOR OF ONF-HALF TO THOMAS v S. IRELAND, OF SAME PLACE.

SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 239,824, dated April 5, 1881. Application tiled January I 1881. (Model.)

To ali whom it may concern:

Be it'known that I, JOHN B. MORRIS, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Shutter-Fastener, or

5 Self-Locking Ilatch or Bar for Window-Shutters, of which the following is a specification.

My invention is especially designed for use 4 on inside window-shutters, and relates to a peculiarly-formed gravitating latch or bar,

'ro with which is associated a catch ordog, which automatically locks said latch in the act of closing the same. In the accompanying drawings, Figure lis a front elevation of my improved shutter-fasteningin its closed condition. Fig.2 is a top View of the same. Figs. 3 and 4are vertical transverse sections of my fastening in its locked and unlocked conditions respectively.

A A may represent portions of two shut- 2c ters; B, a gravitating latch or bar, pivoted at C'to a bracket, E, upon one of the shutters; D, a holder, which receives the free extremity of the latch in the act of closing the same. Theface of the latch is beveled downward, as at b, and upward, as at b'. A lip, F, at the free extremity of the latch B enables it to be easily lifted either forl locking or for unlock- Qlinged at G to the holder D is a gravitat- 3o ing catch, H, consisting of pendant lt and a nose, 7L', that projects nearly rectangularly therefrom. i

`The operation of my fastening is as follows: 'The latch being in the open position, (see dotted lines in Fig. 1,) and Ithe shutters being closed, as indicated in said iigure, the latch is thrown over, and, falling into the holder, easily pushes the nose 7L down sufficiently to pass it, upon which the catch H resumes its normal or locking position, as seen in-Figs. 1, 2, afnd 3. 4o In this position the nose h bears against the upper bevel-surface, b', while the pendent portion h bears aga-inst the bracket-face, as shown in Fig. 3. In the act ot' entering the holder the beveled form b of thelower portion of the latchface facilitates the depressiouof the catchnose h.

Y Should attempt be made to lift the latch Without releasing the dog, the upper bevel-surface, b', coacts with the nose h to eiectually 5o oppose any such elevation of the latch.

When it is desired to open the latch the operator lifts the pendant h, so as to put the catch into the position shown in Fig. 4. This having been done, the latch is easily lifted out 55 of the holder soas to release the shutters.

I claim as a new article of manufacture- The combination of pivoted doubly-beveled `gravitating latch B b b and the holder D, provided with the L-forined gravitating dog or V6o lock-piece H, having the pendant h and nose h', substantially as set forth.

In testimony of which invention I hereunto set my hand.

- JOHN B. MORRIS.
